Abstract (en)
[Problem]Provided is an assembled paper container capable of suppressing leakage of contained matter or seepage of contained matter from a container section of a container main body.[Solution]An assembled paper container 1 includes a container main body 11 including a container section 12, and a resin film 3 covered over an inner surface of the container main body 11. The container main body 11 includes a bottom surface 121, a plurality of side surfaces 122, and a flange section 13. The flange section 13 has a top surface 131 provided with a step 22 extending outward from the container section 12 side, and the step 22 is generated by bonding fold-back pieces 13a, 13b together so as to be mutually overlapped after the assembly. The resin film 3 has a protruding section 31 traversing the step 22 above the step 22 in a part covered with the top surface 131 of the flange section 13 of the container main body 11.
